' Application filed June 22, 1917. Serial No. 176,418.

To all whom it may concern:

Be it known that I, THOMAS H. BIBBY, a

' citizen of the United States, residing at Denver, in the county of Denverand State of Colorado, have invented certain new and useful Improvements in Acetylene Gas Lamps; and I do hereby declare the'follow ing'to be a full, clear, and exact descrlptlon of the invention, such as will enable others skilled in the art to which make'and use the same."

This lnvention relates to improvements-1n acetylene gas lamps of the portable type and has for its primary obj ect to provide a lamp structure embodying several independently operable generators for supplying acetylene gas to a common burner Wherebythe'supply of carbid may be alternately replenished in the holders while the lamp is in operation.

Another object is'thc'provision of means for controlling the admission of water'to the carbi'd holders and for deflecting-the liquid into the ports or passages of the respective partly insection,

hold ers.

Another object is the provisionof a novel type of guard or shield adjustably supported on the burner tips forprotecting the latter and preventing the flame frombeingqblown out by wind or swift air currents. With these and other objects in view, the invention-consists in the'novel construction, combination and arrangement of parts as will be hereinafter specifically described, claimed and illustrated in the accompanying drawing, in which:

Figure '1 represents a the improved lamp," r

Fig. 2 represents aside 'elcvationgthereof front elevation of Fig. 3 represents a fragmentary perspec tive view of the reflector, burner tip and guard therefor, I

Fig. 45'represents a plan view of the lamp, partly in section, the top portioncarrying the waterchamberand burner tip being removed, i

Fig. 5 represents a through the upper part of the"lamp,- and,

Fig. 6 represents a perspective view of the preferred type of holder for the lamp.

Referring to the drawing in detail, wherein similar reference numerals designate corresponding parts throughout the several views, the numeral 5 indicates a hollow cylindrical holder having both ends open and externally threaded to receive the closure it appertains to 7 detail sectional view' convenience in adjustingthe valves.

communication with a filling opening which is closed by a-hinged cap 15'. chamber 14' communicates with a depending extension 16, receiving the stem'17 of a valve 18, which latter; is adapted to engage the lower edge of the tubular extension 16 to regulate or cut off the flow of water therethrough. The upper terminal of the stem '17 is threaded in the top part of the lamp and isdetachably connected with a turning key 19', whereby the stem may beconveniently' rotated toproperly adjust the valve 18 and thus regulate the flow of water to the holder 5.

Deflecting plates 23 are'pivotally supported on pins 24 secured in the' receiver 20 and are actuated, in a manner to be hereinafter described, to control the passage of water to. the chambers 8 and direct it into the desired passage 22 by which it is conducted to the carbid-receiving chamber'S.

. Slidevalves 25' are mounted for longitudinal movement in the slot 26 formed in the top part of theholder 5 and the outer terminals of the valves are turned upwardly,

as indicated at 27, to provide handles for I The slot 26 intersects the passage 22 and the valves 25 may be adjusted independently to regulate the How of water through the ports 8" and into the respective chambers 8, or, if

desired, to completely out 01f the flow of water thereto.

The acetylene gas generated in the chambers 8 is conducted to the interior of the extension 9 by the passages 8 and 22 and finds its way into the gas pipe 27, which is arranged in the top part 13 of the lamp and projects through the conca'ved reflector 28 secured to the front wall thereof. A perforated plate 29, preferably of cylindrical for mation, is detachably secured to the depen d ing extension 16 and supports a wad of fibrous material 30 under the bottom Wall of the top part 13, so asto prevent particles of carbid or other granular substances from entering the pipe 27 and. obstructing the discharge port of the burner tip 31.

A tubular guard or shield 32 is slidably' V and rotatably fitted upon the burner tip 31 and is frictionally held against accidental displacement thereon. The guard is formed with several circular series of relatively small apertures 33, which admit air to the interior thereof to support the combustion of the gas issuing from the dischargeport 34: in the burner tip. Under normal conditions, the guard 32 may be moved rearwardly against the deflector 28 and in this position the front edge thereof terminates in proximity to the front end of the burner tip 31. However, when the lamp is subjected to swift air currents, the guard 32 may be moved outwardly to the approximate position illustrated in Fig. 8, so as to protect s is twisted to provide a loop 88, having connection with a link 89 and substantially T-shaped member 40. A ring 41 is swivelly mounted upon the T-shaped member and is provided with-a loop 42 pivotallyreceiving a supporting hook 43 adapted to be utilized in suspending the lamp from an object. The rear wall of the top part 13 is also provided with a supporting hook 44 to be used insupporting the lamp upon the capof a miner.

The lower terminals ofthe plates23 are engaged by the slide valves 25, so that when the right hand valve is closed, as shown in Fig. 5, the plate 23 engaged therewith is swung inwardly to an inclined position and thus directs the water from the extension 16 into the left hand port 8 WVhat I claim i's: j I

1. In an acetylene gas lamp, a carbid holder, a partition arranged in the holder dividing the interior of the latter into carbid receiving chambers, a water receiver communicating with said chambers, means for supplying water to the receiver, means for alternately directing the water from the supplying means into the respective chambers, and means for controlling the admis sion of water to the chambers and actuating the directing means.

2. In an acetylene gas lamp, a carbid holder, a partition arranged in the holder dividing the interior of the latter into carbid-receiving chambers, means for supplying water to said chambers, means for controlling the admission of water to the chambers,.and means actuated by the controlling means to direct the water into the respective chambers. v

3. In an acetylene gas lamp, a carbid holder, a partition arranged in the holder dividing the interior of the latter into carbid-receiving chambers, a water receiver communicating with the chambers, means for supplying water to said receiver, means for controlling the admission of water to the respective chambers, and means actuated by the controlling means to direct the water into the respective chambers.
